DETAILED DESCRIPTION OF THE INVENTION

With referenced to the abovementioned figures, a modular architectural element was indicated in its entirety with 10, adapted for example to make architectural or decorative structures such as walls, coverings, decorative elements or other items. The elements which the different embodiments have in common were indicated with the same numerical reference.

In general terms, the modular architectural element 10 includes a frame 12 defining at least several side walls of the architectural element.

The architectural element is internally hollow, defining an inner cavity which, according to several embodiments, may house lighting means, to transform the architectural element into a lighting body.

Several examples of frames 12 are illustrated in FIG. 25 and the following, in FIG. 52 a and the following, and in FIG. 70 a and the following. Of course, other, non-illustrated embodiments are also possible.

The frame 12 is internally hollow, at least partially defining the inner cavity of the architectural element. The frame 12 includes contour walls which permit at least one access to the inner cavity of the frame. Preferably, the access to the inner cavity is ensured by the absence of a front and/or rear wall which, together with the frame 12, delimits the inner cavity.

In the example of FIG. 12, a frame with parallelepiped shape is illustrated, defined by two-by-two parallel and opposite contour walls 14 a-d defining a closed perimeter. The access to the inner cavity of the architectural element is ensured by the absence of the front and rear wall. In accordance with a non-illustrated embodiment, the access to the inner cavity may be also be ensured by means of the absence of the single front (or rear) wall.

In the example of FIG. 52 a, a modular architectural element is illustrated which is adapted to make a terminal curvilinear element. In this case, the frame 12 is defined by three contour walls 14 a-c defining an open perimeter. The shape of the contour walls 14 a and 14 c arranged at the end is realized so that the inner cavity of the modular element may be delimited by a single, appropriately shaped front wall. In the case illustrated, the contour walls 14 a and 14 c arranged at the end have a curvilinear edge (for example semicircular or circular). The absence of the front wall ensures the access to the inner cavity defined by the architectural element.

In the example of FIG. 70 a, a modular architectural element is illustrated which is adapted to make a terminal or connection curvilinear element. In this case, the frame 12 is defined by four contour walls 14 a-d. The contour walls 14 a and 14 b are parallel and opposite while the contour walls 14 c and 14 d intersect each other. The shape of the opposite contour walls 14 a and 14 b is realized so that the inner cavity of the modular element may be delimited by an appropriately shaped front wall. In the case illustrated, the opposite contour walls 14 a and 14 b have a curvilinear edge (for example a quarter-circle or a circular arc). The absence of the front wall ensures the access to the inner cavity defined by the architectural element.

In accordance with the invention, two architectural elements are adapted to be fit with each other at one contour wall of the respective frame 12 and to be coupled to each other by means of removable coupling element 16 which cross the respective fit contour walls of the two adjacent architectural elements. The positioning of the removable coupling element is permitted through the inner cavity of the architectural element, made accessible in the frame as previously described.

In accordance with a possible embodiment, the removable coupling element 16 includes a coupling element or key 18 which extends along a longitudinal direction 20 in order to cross two adjoining contour walls, belonging respectively to adjacent architectural elements. With 22, a slot of a contour wall is indicated, adapted to receive the key 18. In several illustrated examples, two slots are foreseen on one contour wall.

Advantageously, the slot and the key have respective transverse sections adapted to define at least two mutual positions of the key and slot corresponding with an insertion position and a coupling position. Preferably, the mutual insertion and coupling positions of the key and slot are obtained by means of rotation of the key itself.

In particular, the slot 22 has a transverse section (or shape) which extends predominantly in a transverse direction (with reference to the longitudinal direction of the key) to form at least one lobe 24. In the figures, a slot is illustrated defining two opposite lobes 24.

Similarly, the key 18 has a transverse section which predominantly extends in a transverse direction with reference to the longitudinal direction of the key itself, forming at least one transverse lug 26. In the figures, a key is illustrated defining two opposite transverse lugs 26. In accordance with the embodiments illustrated for example in FIGS. 1-10, the key 18 includes a central pin 28 from which the two diametrically-opposed transverse lugs 26 extend.

With 30, a grip element is indicated which is arranged at one end of the key, for example on the opposite side with respect to the transverse lugs 26, and preferably provided with a flange 32 adapted to abut against the contour wall through which the key is inserted. In other words, the flange 32 has greater transverse dimensions than that of the slot 22.

The length of the key 18, or central pin 28 if foreseen, is such that the transverse lugs 26 are inserted in the slot 22 of the adjacent architectural element and, following for example a key rotation, abut against the inner surface of the respective contour wall.

In accordance with a possible embodiment, the contour walls of the frame 12 include an edge 34 which is raised outside the frame itself, delimiting a hollow space 36. Advantageously, the key 18 may include at least one additional transverse lug 38, preferably two additional transverse lugs 38, arranged in an intermediate position along the longitudinal direction of the key. In particular, the additional transverse lugs 38 are arranged between the grip element 30 and the transverse lugs 26 and extend along the same transverse direction of the transverse lugs 26. In the case the pin 28 is foreseen, the additional transverse lugs 38 extend from it along the same radial direction of the transverse lugs 26. In particular, the additional transverse lugs 38 are adapted to be arranged between two contour walls of two adjacent architectural elements, at the hollow spaces 36.

In accordance with a possible embodiment, the key includes a portion of stopping elements, adapted to define the relative coupling position between key and slot, and preferably associated with the grip element 30. In the case in which the flange 32 is foreseen, the stopping elements may be realized by means of teeth 40 of the flange itself adapted to abut against notches 42 made in the inner surface of the respective contour wall when the key is in coupled position.

Advantageously, the slots of one contour wall are arranged so to permit making a wall wherein the architectural elements are arranged in a grid pattern or else alternated and staggered by half a length between the two rows of contiguous architectural elements.

In accordance with a possible embodiment, the access to the inner cavity of the architectural element is closed by means of at least one closure panel 44 adapted to be removably mounted on the frame 12. In accordance with the preceding description of several frame embodiments, the closure panel 44 defines a front and/or rear wall of the architectural element.

For example, the architectural element comprising the frame of FIG. 25 foresees the use of two closure panels defining a front wall and a rear wall, respectively (FIGS. 34 and 35 or FIGS. 36 and 37). In accordance with a non-illustrated embodiment, the contour walls of the frame may also include the rear wall, and only one closure panel may be foreseen adapted to define for example a front wall of the architectural element.

According to the additional example of FIG. 52 a, the closure panel 44 is realized by means of a curvilinear wall which is adapted to the shape of the contour walls 14 a and 14 c arranged at the end of the frame. Preferably, such closure panel defines the front wall of the architectural element.

According with the last example of FIG. 70 a, the closure panel 44 is realized by means of a curvilinear wall which is adapted to the shape of the opposite contour walls 14 a and 14 b. Preferably, such closure panel defines the front wall of the architectural element.

In accordance with a possible embodiment, the closure panel 44 is mounted on the frame 12 by means of a snap coupling, preferably realized by means of teeth 46 and hollow spaces 48. The teeth 46 are preferably made in correspondence with an elastic or deformable structure 50 which permits the snap coupling between the closure panel and the frame. In the embodiment illustrated in the figures, the teeth 46 are associated with the closure panel while the hollow spaces 48 are made in the frame, although the opposite is also possible. Preferably, the hollow spaces 48 extend for the entire length of the respective contour wall, leading to the opposite side in order to permit access to the tooth 46 and to simplify the dismantling.

In accordance with a possible embodiment, the coupling between the closure panel and the frame is further improved due to the presence of a form coupling which extends along the edges of the closure panel and frame, adapted to be mutually fit. According to the embodiment illustrated in the figures, the form coupling is realized by means of at least one rib 52, for example realized along the edge of the closure panel, adapted to be inserted in a corresponding seat 54, for example made along the edge of the frame adapted to receive the closure panel. In accordance with a non-illustrated embodiment, the rib is realized on the frame, while the seat is made in the closure panel. In several embodiments, for example with reference to FIG. 60 b, the rib and the seat may be interrupted, or they may extend with continuity along the respect edges of the closure panel and frame.

In accordance with a possible embodiment wherein it is foreseen that the hollow spaces 48 extend for the entire thickness of the respective contour wall, leading to the opposite side, a release accessory is indicated with 56 including an elongated body 58, from which at least one tab 60 extends which is adapted to be inserted in the respective hollow space 48. Preferably, as many tabs are foreseen as there are hollow spaces, so to simultaneously release all of the teeth 46. The figures illustrate two possible embodiments of the release accessory, in relation with the number and arrangement of the hollow spaces.

In accordance with a possible embodiment, the closure panel includes a raised outer edge 61 a which define a hollow space 61 b, for example adapted to receive a mosaic decoration. Preferably, the mosaic decoration has the same thickness of the raised outer edge 61 a, so that the surface of the architectural element is flat.

In accordance with a possible embodiment, the architectural element moreover includes at least one cover panel 62, adapted to be mounted on the outer surface of contour walls of frames which, in the overall structure generated by the coupling of a plurality of architectural elements, are arranged with free ends and are therefore visible. The cover panel insulates the inner cavity, closing the slots 22 and possibly restoring the continuity of the outer surface of the architectural element.

The cover panel 62 preferably has a shape analogous to that of the respective contour wall, or for example adapted to be inserted in the hollow space 36 when the edge 34 is foreseen. Advantageously, snap coupling means are foreseen, for example realized by means of additional teeth 64 and additional hollow spaces 66. In the illustrated examples the additional teeth extend from the cover panel while the additional hollow spaces are made in the frame, although the opposite is also possible. Preferably, the additional hollow spaces 66 cross the entire thickness of the related wall, leading to the opposite side in order to facilitate the dismantling of the cover panel. Also in this case, a release accessory may be advantageously foreseen, as previously described.

With reference to the attached drawings, the first embodiment illustrates an architectural element of parallelepiped shape. The shape may be of multiple types, for example in cubic, wave, arched or wedge shape. In particular, the first embodiment illustrates an architectural element adapted to realize a central part of the final structure.

The second embodiment illustrates a terminal architectural element. The shape of the end may be curvilinear, pointed, square-cut or in another form.

The third embodiment represents a terminal or connection architectural element. The quarter-circumference arched shape is particularly advantageous for making, for example, columns (FIG. 70 b) or connections between walls which extend in different directions.

Below, the mode of use of the above described architectural elements is described.

Two frames of two architectural elements are set side by side in correspondence with two respective contour walls. When the two contour walls are fit together, the respect slots 22 are mutually facing. The lack of a front or rear wall of the architectural element permits access to the inner cavity and to the slots 22 in order to insert the coupling means, in particular the key 18. Grasping the grip element, the key is inserted in the slots of the two contour walls until it arrives on the opposite side. The angular position of the key with respect to the slot is such to permit its insertion. According to the illustrated embodiment, by means of a key rotation (for example corresponding to about 90°), one obtains the passage from the insertion position to the coupling position, wherein the transverse lugs 26 abut against the inner surface of the contour wall opposite the wall wherein the key was inserted. In case additional lugs 38 are foreseen, the rotation of the key also brings these lugs into coupling position, between the two contour walls, or rather inside the hollow spaces 36. Preferably, the rotation of the key is delimited by stopping elements. In the illustrated examples, the teeth 40 abut against the notches 42 defining the coupling position.

When the frame is coupled to adjacent frames by means of insertion and rotation of the respective keys, the access to the inner cavity of the architectural element may be closed by means of the closure panel(s), preferably snap mounted as previously described.

If the frame corresponds to a free end of the structure which one wishes to make, appropriate cover panels may be snap locked at the contour walls which face outward, in order to cover the slots 22 and to restore the outer surface aesthetics and continuity.

For the built structure's dismantling, it is possible to work backwards with respect to that described above. In other words, the closure panels, and possible cover panels, may be dismantled for example by means of suitable release accessories which release the coupling between the teeth 46 and the hollow spaces 48. Subsequently, the keys are brought back into insertion position, for example by carrying out a rotation opposite to that previously described. Unthreading the keys from the respective slots, the frames result free and independent.

From the above, one may appreciate how foreseeing a modular architectural element as previously described permits satisfying the aforesaid need to easily and quickly make architectural structures which are adapted to different environments and with multiple aesthetic effects. Such structures may also be easily and quickly dismantled or modified.

Simultaneously, it is possible to satisfy the additional need of obtaining solid and secure structures, wherein the coupling between the architectural elements is reliable and equally distributed over all contour surfaces. Such aspect is advantageously obtained due to the presence of coupling means which cross the fit contour walls and which may also be positioned in additional points along the contour wall itself.

A further advantage of the architectural element according to the invention lies in the unusual structural simplicity of the same, which permits its production at a very low cost.

The aspects described as further possible embodiments, improving the stability and simplicity of use of the invention, in addition to consequently improving its aesthetic appearance.

In accordance with a possible embodiment, the architectural element according to the invention includes a frame 12 provided with contour walls defining several of the side walls of the architectural element. Moreover, the architectural element includes at least one closure panel 44 and/or at least one cover panel which may be removably associated with the frame, as previously described.

Preferably, the closure panel 44 and/or the cover panel include respective hollow spaces 32, 61 b which house a decoration, for example a mosaic decoration.

The possibility of substituting a wall of the architectural element or covering a contour wall of the frame permits obtaining innumerable surface decorations on a same frame or on several frames already coupled together, foreseeing coupling means as previously described.

It is clear that variations and/or additions may be foreseen to that described above and illustrated, for example regarding the shapes and size of the frames, panels, coupling means and other components of the architectural element.
